MECHANICAL MOVEMENT FOR OPERATING RAILWAY-SIGNALS.

SPECIFICATION forming part of Letters Patent No. 267,184, dated November'7, 1882;

Application filed March 3,1882. (No model.)-

To all whom it may concern Be it known that I, ROBERT P. GARSED, acitizen of the United States, residing at Norristown, in the county ofMontgomery, State of Pennsylvania, have invented a .new andusefullmprovementin Mechanical Movements, which improvement is fully setforth in the following specification and accompan; ing drawings, inwhich- Figure 1 is a side elevation of the mechanical movement embodyingmy invention. Fig. 2 is a top or plan view thereof. Fig. 3 is an endView thereof. Fig. 4 is a front view of a modification. Fig. 5 is afront elevation of another modification.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of means, substantially as hereinafter described,whereby a rod attached to certain mechanism is always operated in thesame direction regardless of the forward or backward motions of a car,engine, or other object to which the device is applied.

Referring to the drawings, A represents a wheel mounted on a movingbody-such as a locomotive-engine, tender, or other proper part of atrain-and adapted to engage with a projection located on the bed of therailroad, and thus be rotated.

To the hub or central collar or side of the wheel is attached a salientarm, B, which pro jects radially, or may project tangentially,

therefrom, and is so disposed as to strike a tappet, G, which is pivotedto the carer locomotive.

To each end of the tappet G is secured a chain, cord, or other flexibleconnection, D, the ends of the two connections opposite to the tappetbeing secured to a pivoted or sliding bar, rod, or crank-arm, E, whichis properly sustained on the car or locomotive. The rod E is attached ina suitable manner to devices to be operated on the car, engine, &c.,such as the hell or whistle, the throttle-valve, or airbrakes thereof.

In cases where it is desired to signal the engineer-such as when theengine has reached or is about to reach a switch which may be displaced,or the train is to be stopped or slowed--a projection on the road-bed israised, either automatically by the mechanism of the switch or by aroadman, so as to engage with or strike the wheel A, whereby the latteris rotated. The arm B, moving with the wheel, strikes the tappet G andturns it a sufficient distance so that one of the connections D is drawnforward, and the rod E. is thereby advanced. The other connection, beingflexible, yields or slackens, so that it does not interfere with theadvance motion of the rod. As the rod is connected to devicesnamed inthe present case-viz., the bell or whistle, throttle-valve, orair-brakesaid devices will be operated and the attention of the engineerdirected to the state of the case, so that he may avert the danger orcause the object of the signal to be attained. The parts may be restoredto their normal positions by pushing back the rod E;

but the weight of the connections D D may be sufficient to accomplishthe same, or springs may be employed for the purpose.

It will be seen that when one connection is drawn forward the otherconnection is slackened or yields, as has been stated. Conse quently thedirection of motion of the tappet does not; vary the direction of themovement of the rod E. The car or locomotivemay run backward, and thearm B thus strike the side of the tappet opposite to that first stated;but the rod E is moved in but one direction, whether the car orlocomotive is advancing or backing, so that the devices to be operateddo not fail in their execution in either direction of the passage of thetrain or object to which the device is applied.

In Fig. 4 the arm B is connected to a part of the pivot of the tappet O,and carries a bevel-wheel, which meshes with a bevel-wheel or teeth onthe wheel A, and in Fig.5 the arm is connected to one end of the tappet,and is engaged by a cross-bar or projection on the wheel, the operationof the rod E being thereby the same as that hereinbefore set forth.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A rotatable wheel and striker or its equivalent operated thereby, incombination with a tappet and rod and flexible connections intermediateof the tappet and rod, whereby by the operation of the tappet in eitherdirection the direction of motion of the rod is not varied,substantially as and for the purpose set forth.
